It penetrates on plane of refraction 412 and refraction occurs and enters in lens body 41, the light entered in lens body 41, which is irradiated to, to be all-trans
It after penetrating face 413, is totally reflected on fully reflecting surface 413, i.e., light is radiated on fully reflecting surface 413 and will not reflect, i.e.,
The light being irradiated on fully reflecting surface 413 will not be emitted to outside lens body 41 via fully reflecting surface 413.Therefore enter lens
Light in main body 41 will finally be exposed to outside lens body 41 by being emitted plane of refraction 414 because of refraction.
Since the light of side is finally all projected by the reflection of fully reflecting surface 413,100 phase of optical module of the application
Than the side in light guide plate and the light of internal dissipation can be used, therefore for the prior art using light guide plate
Can have stronger brightness under the premise of constant power.
Central incidence plane of refraction 411 is formed in being right against on the face of light source 3 of lens body 41, the i.e. incident plane of refraction in center

When assembling panel light, first substrate 2 is fixed on the bottom wall 11 of mounting plate, multiple light sources 3 are then fixed on base
On plate 2, it is adapted finally by the fixation detent 416 on optical lens 4 and the fixed card slot on mounting plate 120, by optical lens
Mirror 4 is fixed on mounting plate, to complete the assembly of the main structure of panel light.The light source assembly of the application is compared to existing skill
Art is assembled simpler due to no setting is required light guide plate, and cost is less expensive.
Central incident plane of refraction 411, side incidence refraction are formed on the lens body 41 of optical lens 4 in the application
Face 412, fully reflecting surface 413 and outgoing plane of refraction 414, so that the light that light source 3 issues is via central incident plane of refraction 411, side
It after incident plane of refraction 412 enters in lens body 41, is projected outside optical lens 4 via outgoing plane of refraction 414, or via being all-trans
Penetrate face 413 projected again by outgoing plane of refraction 414 formed outside optical lens 4 area source 3 and shine uniformly, realize light guide plate and exist
Effect in panel light, the light guide plate to remain high to cost play substitution effect, reduce the cost of panel light, improve
The market competitiveness and cost performance of panel light.
It is noted that in this application, " generally " means, ten tap on dimensional values therebetween
Closely.However it will be apparent to those skilled in the art that it is present such that the positional relationship of object exists due to objective factors such as error, tolerances
Small scale or even microcosmic angle are difficult to just be constrained.Even if therefore slightly there is point mistake in size between the two, positional relationship
Difference can't also produce bigger effect the realization of the technical effect of the application.
Finally, it will be understood by those skilled in the art that in above-mentioned each embodiment, in order to keep reader more preferable
Ground understands the application and proposes many technical details.But even if without these technical details and it is based on above-mentioned each embodiment party
The various changes and modifications of formula can also realize each claim of the application technical solution claimed substantially.Therefore, exist
In practical application, can to above embodiment, various changes can be made in the form and details, without departing from spirit herein
