(Points of interest)
In recent years, high-power LEDs of COB (ChiP On Board) type have advanced technological development in terms of performance, the luminous efficiency has improved year by year, and high-power products from 10W class to 100W class or more have appeared, and large lighting Although application to lamps is also being realized, when using a high-power COB type LED for large-sized lighting, compared to other light source lamps, the amount of light cannot be secured by itself, so it is necessary to use multiple combinations, If efficient heat dissipation and light distribution control of each LED are not improved, it is difficult to ensure high efficiency and long life.

    Compared with conventional fluorescent lamps and HID (High Intensity Discharge Lamp), the LED has a much longer life, but the life of the housing that accommodates it is more than twice that of the LED. Therefore, replacement of the LED light source is indispensable for economical use, and a structure with improved maintainability is required.

(Conventional technology)
Reflecting this situation, proposals that can be used to overcome this situation are not unheard of.
For example, as represented by those proposed in the following Patent Documents 1 (1) and 1 (2), heat radiation grease and heat radiation are provided between a substrate on which an LED is mounted and a heat radiation component on which the LED is mounted. Some LED modules have improved heat dissipation efficiency by interposing rubber or the like.

The applicant of the present application has been developing a large-sized illumination lamp for many years, as seen in Patent Document 1 (3), which has been used for lighting of tunnels and buildings. To judge whether cooling performance can be improved by interposing heat-dissipating grease or heat-dissipating rubber between the LED module as shown in 1 (2) and the heat-dissipating component on which it is mounted. However, the problem remains that it is not possible to improve a plurality of LED light distribution controls and maintainability in a large illuminating lamp alone.

As shown, when the mounting rail 5 is not provided, when the Ta ambient temperature is 25 ° C., the Tc case surface temperature is 64 ° C., the Tj junction temperature is 94 ° C., and when the Ta ambient temperature is 40 ° C., the Tc case surface temperature is 79 ° C. Compared to 109 ° C., the heat dissipation performance can be greatly improved.

    In the maintenance work of the LED light source unit 12, all the parts can be replaced by simply removing the screws S, S,... Of each part. Can be easily combined with screws S, S,... Again.

    Since the LED lamp 1 of the present invention having the above-described configuration has greatly improved heat dissipation performance, it can greatly extend the durability life of a large number of mounted COB type LEDs 3, 3,. The LED light source unit 12 in which a plurality of LED modules 2, 2... Are grouped together can be attached to and detached from an appropriate place in the type lamp body 10, and is being assembled and maintained during manufacturing. As a result, it is possible to significantly improve the work efficiency of the disassembly and assembly work, greatly reduce the production cost and maintenance cost, and make it much more economical from installation to maintenance / inspection.

(Conclusion)
As described above, the LED module, the LED light source unit, and the LED lighting device using the LED module according to the present invention can achieve the intended purpose universally by the new configuration, and can be easily manufactured. Compared to the lamp technology that employs fluorescent lamps etc., the service life can be greatly extended, the frequency of maintenance can be further reduced, and it can be made much more economical. In the past, it has been necessary to spend a great deal of money on the installation and maintenance of lighting fixtures, and for many years it has been difficult to create a budget. Manage tunnels such as motorways and highways as well as public organizations that want to reduce the lighting management costs of various general roads such as municipal roads. Even in companies and road management industry, it is highly regarded, available over a wide range, is expected to be those that continue to spread.
