Description
Technical Field
The invention belongs to the field of device sealing, and particularly relates to a light leakage-proof and illumination-resistant sealing element and a light-emitting device using the same.
Background
Currently, the light emitting device needs to be provided with a hole for connecting a power line or other requirements, and the hole needs to be sealed after the hole is formed. The sealing member is usually made of a polymer material such as rubber. The sealing function of the sealing element is that the sealing element generates elastic deformation to generate contact pressure on a sealing contact surface, and when the contact pressure is larger than the internal pressure of a sealed medium, leakage does not occur, so that the sealing effect is achieved. The device based on the seamless sealing can also prevent light from irradiating from the opening gap to cause light radiation (such as laser radiation). However, the gasket has the defects of limited high temperature resistance and illumination resistance, when the low molecular polymer inside the gasket material becomes extremely active under illumination and high temperature environment, volatile matters are easily volatilized to cause pollution inside the light emitting device, for example, the volatile matters are easily attached to the surface of the optical member to cause low light efficiency and even burn the optical member; or attached to the sensing device causing a sensing failure, etc. This is particularly evident with colored gaskets, especially dark colored gaskets such as black, which absorb light easily to cause volatilization. Therefore, the gaskets used in the prior art in the light-emitting device are all transparent gaskets. However, the transparent sealing gasket causes direct transmission of light to be emitted to the outside of the light emitting device, and when the light emitting device adopts laser as a light source, laser radiation is caused to cause injury to human eyes. International standard IEC60825-1 "safety of laser products: part 1: the safety level is divided into four levels according to the safety degree of the laser product to a user, wherein the safety level is clearly specified in the classification and requirement of the equipment:
(1)1 st laser
Level 1 lasers are more generally invisible laser radiation (radiation wavelength greater than 1400nm) generated by infrared lasers or laser diodes, and the radiation power is generally limited to 1 mW. Such lasers are safe under reasonably predictable conditions, they do not produce harmful radiation and do not cause fire.
(2) 2-level laser
The 2-level laser generates continuous or pulse visible light radiation with the wavelength of 400-700 nm, the radiation power is generally low, and the radiation power of the continuous light is generally limited to 1 mW. Such laser products typically provide eye protection from avoidance responses including blink reflex.
Level 1 or level 2 laser products are commonly used for presentation, display or entertainment purposes, and are also commonly used in mapping, alignment and leveling applications.
(3) 3-level laser
The 3-level laser is classified into 3a level and 3b level. The grade 3a laser products can be seen or not seen, generally, the laser can not be harmed by the naked eyes in short time observation, but when the laser is observed by an optical instrument such as a microscope or a telescope, the laser beam can cause damage to eyes. The 3a class of lasers typically provide eye protection from avoidance responses including blink reflections, and the diffuse reflections of this class of lasers are generally not hazardous and do not pose a fire hazard. The 3a visible laser output power is limited to 5 times the 2 level laser output power, i.e. 5 Mw; the invisible laser output power is limited to 5 times that of the 1 st order laser.
The 3 b-level laser specifies that the output power of the continuous laser is more than 500Mw, and the single pulse energy of the repeatable pulse laser is specified to be 30-150 mJ (which varies according to the wavelength); laser light of class 3b can cause damage to the eye and skin, as can diffusely reflected light of this class.
(4) 4-level laser
The continuous or repeatable pulse laser with the average power of more than 500mW is classified into 4 grades, the laser energy output by a single pulse is 30-150 mJ (variable according to the wavelength), and the laser wavelength is visible or invisible. The power of the 4-level laser is enough to cause the eyes or the skin of a person to be injured instantly. The diffuse reflection of the laser light is as harmful to the eye or the skin. The 4-level laser can burn combustible materials, and the possibility of fire is caused when the laser power density reaches 2W/cm 2.
The 3-grade or 4-grade laser product is generally applied to the fields of scientific research experiments, engineering research, laser engraving, laser welding, laser cutting processing and the like which need high-energy laser radiation.
In summary, it is shown that the laser product must satisfy the requirement of grade 2 or above, and the existing product cannot satisfy the requirement of grade 2 or above because the transparent sealing member can transmit light. Meanwhile, the 2-level laser product still needs to be provided with eye protection, and the requirement of 1-level laser safety is put forward in many international application occasions. Against this background, there is an urgent need to solve the problem of laser radiation caused by the light transmission of the transparent sealing member.
Therefore, in view of the above-mentioned disadvantages, there is a need to provide a new sealing member and a light emitting device, so as to solve the technical problems that the sealing member in the prior art cannot block the light beam emitted by the light source, may cause radiation to cause damage, and the sealing member itself generates substance volatilization to cause pollution to the internal components in the sealed space.
